What is the equation of a line perpendicular to

Valentin [98]

Since the given line

$y = \frac{ 1}{4} x - 3$

has slope
$= \frac{1}{4}$

The equation of the line perpendicular to it must have a slope which is the negative reciprocal of ,
$\frac{1}{4}$
The slope of the perpendicular line
$= \frac{ - 1}{ \frac{1}{4} } = - 4$
Using the slope intercept form,

$y = mx + c$
We substitute
$- 4$
This implies that,
$y = - 4x + c$
Since

$(-2,4)$
lies on this line , it must satisfy its equation.

That is

$4 = - 4( - 2) + c$

This implies that

$4 = 8 + c$
$4 - 8 = c$
$c = - 4$

The line therefore has equation,

$y = - 4x - 4$

Which phrase is best represented by the algebraic<br> expression<br> x/4 -2

Ber [7]

Answer:

D) 2 less than the quotient of x divided by 4

Step-by-step explanation:

Since it's x/4 there has to be a quotient or division involved in the sentence, which eliminates A and B. Since there's a -2, C is eliminated since it doesn't include 2.

Kkkkkkkkkkkkkkkkkkkkkkkk

Aloiza [94]

The formula for slope is y = mx + b
y is the y value, m is the slope, x is the x value, and b is the y intercept.

The equation given for line e is
$y = \frac{ - 9}{2} x + 7$
Therefore the slope of line e is -9/2
Line f is parallel and parallel lines have the same slope.

So the slope is line f is -9/2.

The picture isn't that clear and I can't really tell if it's-9/2 or 9/2.
But whatever it is, the slope of line f is the same as the slope of line e because they are parallel.
Good luck!
